Components of catalysts for use in polymerizing and catalysts prepared therefrom

摘要

There are disclosed new starting components for use in preparing catalysts for the polymerization and copolymerization of olefins. The new starting components are compounds having the general formulae R2AlOR'' and/or RAl (OR'')2, in which R represents alkyl radicals containing 1 to 12 carbon atoms and R'' has one of the following structures:
